- 40 A further object of the invention .is' Usually in ovens a separate front or door broadly to construct an oven 'that has its frame 1s used, the said frame provided with side and top walls enameled to furnish a door openings. In the. construction here finished enameled product with only a narshown, the separate front frame or frames row finishing bead 'of another color surare completely eliminated. I accomplish 95 sounding the said doors. this elimination by having the front edge A further object of the invention is to of these walls with integrally formed conconstruct the top and side walls of an oven structions. For instance the front edges of -with integral inwardly bent portions both'the top and side walls are doubled at against which the door isficlosed,-the side right angles to-thesaid-walls, as shown at "W walls extending from top to 'bottom of the 11, which is in a plane with the face of the wall, and 'a narrow connecting piece attached oven which walls are then doubled inward atright. angles as shown at 8, then again doubled at ri ht angles in a line with the face of the oven as hown at 9, and again; doubled inward at right angles as shown at 10.

These integral with the walls 1 and 2.- By doubling these walls as described, first a narrow outer face 11 is formed around the doors, and a recess 12 is formed in a direction parallel with. the doors and the front face of the oven. This recess 12 preferably extends entirely around'the face of the oven, and the depth of this recess is regulated by the length of the doubled or leg portion 8.

This leg portion 8 is preferably of a length equal to the thickness of the door whereby the door whenit is closed in the said recess,

The object of bending inward the inner edge'of the recess 12 as shown at is for giving the said portion strength and rigid- Figure 7, it will be noted of the doubled portion of the side walls 2 is bent inward a sl ght distance as at 13 suflicient forthe wall of the By reference to the sidewall, and where these parts overlap they are provided with registering bolt openings 14 and 15 through which a suita lebolt-.10

The inwardly bent portion 13 extends across the upper end of the wall 12 and also the upper end of the surrounding rim. portion 11.- To add rigidity to the side wall 2 its upper, end is bent horizontally inward as at 26, anl the front end of this inwardly front vertical edge of the bent part or flange 26 is cut away as shown at 27 for the purpose of enabling the bent portions 8, 9 and 10 to side wall 2'. Usually ovens are provided at their lower portions with what is termed in the art as the broiler part of the oven. 'When the oven with this usual broiler portion as is provided the door openings are controlled here shown,

by the broiler door 6. In such an instance I I provide a cross member 16 that is so shaped as to fit the irregular bent portion of the side wallsand to -..extend out in the same plane as the narrow rim 11, and will have substantially the same exposed width 17 as the width of the rim 11.- Th s cross piece 1.6 has its lower edge re'cessedas. shown at 18 a distance equal to the recess lower edge of 12, whereby a complete closing recess for the broiler door 6 is provided, while the upper face 19 of the cross piece 16 closes tightly with the the oven door 5. piece 16 is preferably composed of cast metal, its inner edge being essentially parts as here shown are preferably. M

' through these pieces and into an opening 25 16. In that man- =ner the cross piece, .21 and the wall 12' are united detaehably toand 15, the periphery portion 1 to fit this doubled portion of passes for fastening the parts be formed in the applied to the ove This cross U-shaped as illustrated at 20. The ends of this cross piece 16 are cut .by a screw that passes through a reinforcing strip 21 and the wall of the recess 12,j

the said parts ings 22 and 23, and the screw 2 1 passes formed in the cross piece thereinforcing strip gether. As here shown the outer edge 28 of the reinforcing strip 21 is bentrlaterally outward as shown in Figure 5, resting against the inner side of the bent'portion 8.

- By referring to Figures 6 and. 7 it will be observed that in forming of the openings are countersunk, and that the head of the screw or bolt 10 is made flat and fits in the counterthe openings 14 having registering screw opensunk portion of the opening. In this way the head of the bolt is flat with the surface 12, and does'not interfere at all with the closing of the door 5.

Referring now to the top part 1, its front horizontal edge is formed to correspond with 0 i the formation of the vertical edge of the side wall 2, and are so constructed that there is formed a horizontal wallcorresponding to the. wall 12 against which the door closes. The sides 29 of the top portion are turned downward and rest outside of the upper part of the side walls 2, s also bent downward to receive the upper inwardly bent end 31 of the rear wall 32 of the oven 2. i i

A separate splash side board 33 is arranged between the top 1 and the open burner frame while the rear edge 30" 34. This is located at the upper part of the side wall 2, and is enameled to-correspond to the enameling of the doors 5 and 6, the top wall 1 and the outer side wall 2. In this man-' ner the wall 33 is made detachable where:

by it can be separately enameled and then The front end 35.0f the wall 33 is formed into an outwardly bent bead portion, the outer edge 36 of this bent portion extending into a vertical groove.37 made in the side wall- 2 of the oven. The obiect of thi nstruction is to make the outer edge of the wall 33 fit tightly the wall 2 and to conceal the outer edge 36'. The lower edge 38 of the wall 33 as shown by dotted line in Figure 1, passes jacent wall of the open burner frame 34: while its upper edge 39 extends upward between the part 29 'of the top 1 and the upper end of the side wall 2. This manner of holding the wall 33 in position 'avoids the necessity of bolts of any kind for that purpose, while at the same time it insures that the said wall will be held tightly against the wall 2. The rear end of the wall 3 3'is preferably provided with an outwardly bent bead por-- downward between the adtion 40 that is similar to the part 35 at its 1,eos,211

front end and which also fits into a groove jv similar to the groove 37 that ismade in the ameled.

front end of the wall 2.

For the purpose ofmaking a finish'for'the iear end of the top 1 I provide a vertically arranged U-shaped member 41 thathas its lower end 42 L-shaped and which is held to the described parts of the-oven by means of suitable bolts 43.

, It will be understood from the foregoing description that the inwardly bent flange on the top' portion 1 corresponding to 10, is cut away a short distance and also that part corresponding to 11 and 8 cut away to enable the top portion to be properly placed in position on the side of the walls to bring the surrounding wall 12 flush all around.

By forming the front edges of the side wa'llsand of the top walls in the manner herein described, it will be observed that I- have entirely eliminated the necessity for .a detachable door frame, while at the same time I have provided a recess sufliciently deep to receive the oven doors and to produce a strong structure with a finished appearance. I also am enabled to make a structure that is relatively deep as compared to the ordinary structure.

.I am also enabled to 'produce a stove which in appearance is without any frontframe and to produce an oventhat is wholly on One advantageof the above defined and illustrated construction as compared with the usual ovens, is that'fall visible bolts and fastenings are omitted from the structure. This makes quite a reduction in the cost of assembling of the structure, as well as in the production of it.

It will be noted in examination of that part of Figure 7 which shows the side wall 7 hent as described, that the bends 8, 9 and 10 make a contour that is substantially Z- shaped. I

While I have. described and have shown many details of construction, I wish it understood that variations may be made in this construction without departing from the spirit and scope of my invention so. long as the changes would -coine within a fair interpretation of the appended claims.
